1872.] ON THE BIEDS OF CELEBES. 203 



An Andaman and a New-Guinea example in my collection are identical. 

 There can be little doubt that this is the 6'. sumatrana. Raffles — a title most inappropriate, 

 but which has priority.

If Mr. Blyth's identifications of the North-African and South-Asiatic species be correct, the 

 range of this Tern extends from Sicily to Madagascar, the coasts of India, of Northern Australia, 

 and the islands of the Malay archipelago, at least as far as Celebes. It must be remembered, 

 however, that Dr. Pucheran (/. c.) has stated that the Abyssinian and Bengal s])ecies differs " par 

 plus de noir dans les remiges et par son bee moins courbe, et par cela meme plus droit." {Conf. 

 Finsch & Hartl. Vogel Ost-Afrika's, p. 830.)
